Try the .appimage version, at least vscodium is coming in many different formats. I personally avoid flatpaks due to size and permission issues (e.g. gimp can’t use its special extra-featured printing panel, which makes it absolutely useless for me as an artist on a flatpak).
Try Flatseal.
Didn’t work.
Probably it’s not a permission problem.
